fix(docker): ship Bedrock auth and current registry (#2982)
## Description

Fixes #1551 and #1692.

Every published Headroom Docker image now installs the existing
`bedrock` extra, so `--backend bedrock` can authenticate with temporary
STS, SSO, and credential-process credentials instead of failing because
`botocore` is absent.

Public Docker instructions now consistently use
`ghcr.io/headroomlabs-ai/headroom`. Several still pointed at the old
personal package, which is frozen at 0.27.0 and caused users to report
that no latest image existed.

## Type of Change

- [x] Bug fix
- [ ] New feature
- [ ] Breaking change
- [x] Documentation update
- [x] Build / CI

## Changes Made

- Add `bedrock` to the standalone Dockerfile default extras.
- Add `bedrock` to all nine root/code/slim/nonroot bake targets.
- Replace obsolete personal GHCR references in README, llms.txt, Compose
guidance, testing guidance, and wiki docs.
- Add release contract tests for Bedrock dependencies and the current
organization registry.

## Testing

- [x] Focused Docker release and Bedrock preflight tests pass.
- [x] Full updater suites pass: 69 tests.
- [x] `uv run ruff check tests/test_release_workflows.py`
- [x] `docker buildx bake --print`
- [x] `git diff --check`

## Real Behavior Proof

Before this change, every published bake target installed only `proxy`
or `proxy,code`, so `AWS_SESSION_TOKEN` selected an unavailable botocore
path. Public copy-paste commands also referenced
`ghcr.io/chopratejas/headroom`, which the existing migration code and
changelog identify as frozen at 0.27.0.

After this change, all nine parsed bake targets install `bedrock`; the
regression resolves that package extra and confirms `boto3` plus
`botocore`. Every public Docker instruction covered by the contract
names `ghcr.io/headroomlabs-ai/headroom`.

## Runtime Rollout Safety

This changes image contents and documentation only; proxy routing and
non-Docker installs are unchanged. Static AWS credentials remain
unaffected. Existing manifests using the deprecated image continue to be
migrated by the established install-state logic. Rollback is a
Docker/bake extras and documentation revert.

## Review Readiness

- [x] Two related Docker blockers batched in one PR
- [x] Regression coverage included
- [x] No unrelated lockfile changes
- [x] Ready for review

feat: add deterministic runtime rollout controls (#1490)
## Description

Establish one centrally resolved, observable, deterministic, versioned
runtime rollout-control mechanism for Headroom. Runtime rollout controls
which behaviors an already-built artifact may expose; it does not select
or qualify a Headroom release/version.

## Type of Change

- [x] New feature (non-breaking change that adds functionality)
- [x] Bug fix (non-breaking change that fixes rollout enforcement
regressions)
- [x] Documentation update
- [x] Code refactoring (no functional changes)

## Changes Made

- Added `RolloutChannel`, `HEADROOM_ROLLOUT_CHANNEL`,
`--rollout-channel`, and a versioned immutable `RolloutSnapshot` shared
by Python configuration boundaries.
- Added schema/policy versions, canonical registry and snapshot SHA-256
identities, per-feature decision reasons, disable precedence, unsafe
qualification poisoning, strict CLI validation, and fail-closed
environment handling.
- Added `headroom rollout status --json`, Python `/stats.rollout`, and
Rust `/rollout/status` runtime provenance.
- Added equivalent Rust snapshot semantics and shared Python/Rust policy
vectors while retaining language-specific feature registries.
- Enforced rollout policy at alternate Python server composition roots
so `HEADROOM_READ_MATURATION=1` cannot bypass its beta gate.
- Preserved typed rollout snapshots across multi-worker serialization
with schema, policy, registry, snapshot-digest, type, and feature-name
validation.
- Made loopback runtime output-shaper updates replace the immutable
snapshot atomically for request readers, retain explicit request/disable
provenance, preserve channel and kill-switch precedence, invalidate
cached stats, and return the effective rollout decision.
- Made `headroom learn --verbosity --apply` report a channel-blocked
update instead of claiming the shaper is live.
- Made explicit CLI feature flags fail loudly when their current channel
blocks them.
- Made persistent interceptor installation select canary automatically,
or reject an explicitly insufficient channel unless the break-glass
override is set.
- Updated architecture, proxy, rollout, learn, and output-shaper
documentation with required channels and hot-reload semantics.

## Testing

- [x] Unit tests pass
- [x] Linting passes (`ruff check .` and `ruff format --check .`)
- [x] Type checking passes (`mypy headroom --ignore-missing-imports`)
- [x] New regression tests added for every corrected behavior
- [x] Rust tests and production-target Clippy pass
- [x] Documentation build passes

### Test Output

```text
Focused rollout coverage suite
57 passed; headroom.rollout + rollout CLI: 98% coverage

Affected proxy/rollout/transform/governance suites
222 passed; 0 failed

Final changed regression suites
100 passed; 0 failed

Cross-module hot-reload isolation regression
6 passed; 0 failed

cargo test -p headroom-core -p headroom-proxy --quiet
headroom-core: 924 passed; 1 ignored
headroom-proxy and integration suites: all passed

cargo clippy -p headroom-core -p headroom-proxy --lib --bins -- -D warnings
cargo fmt --all -- --check
ruff check .
ruff format --check .
mypy headroom --ignore-missing-imports
git diff --check
All passed

cd docs && npm run build
Compiled successfully; 164 static pages generated
```

The unsharded Windows-only CI selection exposed unrelated baseline
failures, principally the existing `sqlite:///C:\\...` URL parser
producing an invalid `\\C:\\...` path. At commit `8e793a80`, all 52
completed GitHub checks passed; the only other conclusions are expected
skips and superseded governance jobs.

## Real Behavior Proof

- **Environment:** Windows checkout on Python 3.13.3 and the current
Rust workspace, based on upstream `main` at `93f2d7a2`.
- **Exact command / steps:** Exercised canary and beta feature requests
through CLI status, Python `/stats.rollout`, Rust `/rollout/status`,
multi-worker payload round trips, loopback `/admin/runtime-env`, real
proxy request shaping before/after hot reload, installer manifest
generation, and shared Python/Rust policy vectors.
- **Observed result:** Stable blocks unstable requests; disable wins
over explicit/default/legacy/unsafe paths; unsafe state reports
`qualification_eligible=false`; worker handoff rejects tampering;
running output shaping changes only when the effective beta policy
permits it; explicit blocked flags fail with actionable diagnostics.
- **Not tested:** Live production traffic requiring provider
credentials, or future artifact qualification/promotion automation
(intentionally out of scope).

## Runtime Rollout Safety

- **Rollout-managed features:** Python `tool_result_interceptors`,
`proxy_output_shaper`, `read_maturation`; Rust `native_bedrock`,
`openai_responses_streaming`, `canary_probe`.
- **Minimum rollout channel:** Registry-defined per feature; process
default is `stable`.
- **Stable/default behavior changed:** No unstable feature becomes
enabled by default. Explicit blocked CLI flags now fail instead of
silently doing nothing.
- **Kill switch / disable path:**
`HEADROOM_DISABLE_FEATURES=<comma-separated feature names>`; explicit
disable has highest precedence, including over the unsafe override.
- **Unsafe override required:** No.
`HEADROOM_UNSAFE_ALLOW_UNSTABLE_FEATURES=1` is break-glass only and
makes qualification evidence ineligible.
- **Qualification impact:** Adds machine-readable policy/snapshot
identities and eligibility; does not implement qualification itself.
- **Rollback path:** Set the named disable list for operational
rollback, lower the channel, or revert this PR.

## Review Readiness

- [x] I have performed a full diff review
- [x] This PR is ready for human review

## Checklist

- [x] My code follows the project's style guidelines
- [x] I have performed a self-review of my code
- [x] I have commented hard-to-understand areas
- [x] I have made corresponding documentation changes
- [x] My changes generate no new warnings
- [x] I added tests that reproduce and prevent every regression fixed
during review
- [x] New and existing affected tests pass locally
- [x] I did **not** edit `CHANGELOG.md`; release-please generates it
from the Conventional Commit PR title

## Additional Notes

Out of scope: artifact candidates, benchmark orchestration,
qualification manifests/gates, promotion automation, release branches,
publication guards, and release-risk classification. Those workflows can
consume the rollout registry digest, runtime snapshot digest, decision
reasons, and qualification eligibility through supported black-box
interfaces.

fix(compress): resolve the /v1/compress tokenizer per model, and document the real contract (#2743)
## Description

`/v1/compress` does no format conversion — callers send whichever wire
shape they already use — but the pipeline pinned **one provider's token
counter for the whole route**.

`OpenAITokenCounter.count_message` walks list content for `text` and
`image_url` only and has **no else branch**, so Anthropic content blocks
contributed literally zero. A 599-token `tool_result` scored 8. A
request that really removed 235 characters reported `tokens_saved: 0` —
so a caller gating on `tokens_saved > 0` concludes compression is broken
while it is working.

Prompted by a Kong integration question ("do you support the Anthropic
native format?"). The answer is that we already did — we just reported
zeros for it, and the docs said otherwise.

Closes #

## Type of Change

- [x] Bug fix (non-breaking change that fixes an issue)
- [x] Documentation update

## Changes Made

### Tokenizer resolution (no hardcoded lists)

Build the derived pipelines with `provider=None` so `TransformPipeline`
resolves the tokenizer from the **per-model registry**. Every registry
tokenizer derives from `BaseTokenizer`, whose `_count_content_parts`
ends in a serialize-and-count catch-all, which means:

- No block type counts as zero, and there is **no per-provider
block-type list to keep in sync**. An enumerated set was the first thing
I tried and it already missed `mcp_tool_result`,
`web_search_tool_result`, `document`, and `thinking`.
- Gemini / Mistral / DeepSeek / Kimi stop defaulting to a tiktoken count
when the registry already has a calibrated counter for them.
- Gateway aliases matching no vendor pattern still count correctly.

`mode="ccr"` now runs a derived pipeline too, for the same reason —
sharing `openai_pipeline` pinned its provider. Costs that mode its own
cold compression cache; correct metrics win.

### Tokenizer selection stays separate from context-limit resolution

Deliberately not welded together. `model_limit` feeds `context_pressure
-> min_ratio`, so letting a tokenizer decision pick the limit table
changes compression aggressiveness: `gpt-4-32k` answered by the
Anthropic table is **8,192 instead of 32,768**, a 4× under-estimate.
`test_tokenizer_choice_does_not_move_the_context_limit` pins the
independence.

### Docs, rewritten from the code

- **`proxy.mdx`** — the loopback-only default and **404-not-403**
behavior, previously undocumented *anywhere* in `docs/` despite shipping
in #2458 explicitly for gateway sidecars;
`HEADROOM_COMPRESS_ALLOW_REMOTE`; all four request fields; the whole
`config` object including every `mode` value and `frozen_message_count`;
`transforms_summary`; the 400/401/404/503 contract; and the timeout
fail-open shape (`compression_skipped` / `skip_reason`).
- **Corrected "never calls an LLM"** — accurate about *generative*
provider requests, misleading for a sidecar operator. Kompress (a
ModernBERT **encoder**, classification not generation) and Magika run
**in-process**, and `HEADROOM_KOMPRESS_ENDPOINT` offloads inference over
HTTP — **real egress**. Now stated explicitly, with
`HEADROOM_DISABLE_KOMPRESS=1` as the structural-only option.
- **Both wire formats documented as accepted**, and removed
`anthropic-sdk.mdx`'s claim that OpenAI format is "the compression
engine's native format" — the exact misconception that prompted this
work. The SDK's conversion is now framed as an SDK choice, not an API
requirement.
- **`litellm.mdx`** had no mention of the endpoint at all, despite the
code naming LiteLLM's guardrail as its primary consumer. Added the HTTP
deployment path, the `HEADROOM_COMPRESS_ALLOW_REMOTE` requirement, and
why to leave `config.mode` unset.
- **`index.mdx`** printed `compressionRatio * 100` labelled "Saved …%",
so a 77% saving displayed as **23%**. `api-reference.mdx` already
defined it correctly, so the docs contradicted each other.
- `openai-sdk.mdx`, `wiki/proxy.md`, `wiki/typescript-sdk.md` — same
corrections; dropped "any HTTP client", "Cloud", and a CacheAligner
claim (it is detector-only).

Broader sweep (`-k "compress or litellm or gateway or guardrail"`):
**1625 passed, 4 failed** — all 4 pre-existing, verified by stashing
this diff and re-running on clean `main` (2 strands hook tests, 1 codex
WS semaphore-tail timing test, 1 unrelated local WIP test).

## Real Behavior Proof

- **Environment:** macOS 26.4 arm64, Python 3.12.6, repo `.venv`, branch
rebased on `upstream/main`.

**(1) Before → after, same request** (60-line grep payload in an
Anthropic `tool_result`):

| model | before | after |
| --- | --- | --- |
| `claude-sonnet-4-6` | `before=28 saved=0` | `before=1223 saved=58` |
| `bedrock/anthropic.claude-3-5-sonnet` | `saved=0` | `before=1037
saved=59` |
| `my-gateway/big-model` (alias) | `saved=0` | `before=1037 saved=59` |
| `gemini-2.5-pro` | `saved=0` | `before=1036 saved=59` |
| `gpt-4o` + OpenAI shape | `before=1225 saved=58` | `before=1225
saved=58` (unchanged) |

All three `config.mode` values verified for each. Response shape
preserved: `type=tool_result`, `tool_use_id` intact.

**(2) Counter-level root cause**, 6.8 KB body, `count_message()`:

```text
OpenAITokenCounter    string-content -> 1406    tool_result block -> 5
registry (BaseTokenizer) claude       tool_result=408  thinking=418  mcp_tool_result=421
                                      web_search_tool_result=421  document=422
```

**(3) Every documented behavior asserted against the running app** — 13
checks, all PASS: 400s for missing `messages`/`model`, invalid
`config.mode`, and all four invalid `frozen_message_count` forms; 200
for valid ones; non-dict `config` ignored; bypass and empty-messages
omit `transforms_summary`; success returns exactly the 8 documented
keys.

- **Not tested:** the docs site was not built (`docs/node_modules`
absent) — MDX was checked for balanced `<Callout>` tags only, so a
reviewer with the site running should eyeball rendering. No live
gateway/Kong request; verification is via `TestClient` against the real
ASGI app.
- **Note:** `HEADROOM_DISABLE_KOMPRESS` is read into `ProxyConfig` at
`server.py:4919` and by the CLI, not by `create_app(ProxyConfig(...))`
directly — I confirmed `disable_kompress=True` does reach the derived
pipeline.

fix: remove rtk and lean-ctx CLI context tools (#2677)
## Description

Removes both third-party CLI context tools — **rtk** and **lean-ctx** —
and with them the context-tool selector itself. Headroom no longer
downloads, installs or configures either one, and there is no
replacement.

The previous pass (#2344) gated only three entry points inside
`headroom/cli/wrap.py`. That left the feature reachable in practice:

| Gap | Effect |
|---|---|
| `scripts/install.sh:1544`, `install.ps1:1681` | Ran `rtk init --global
--auto-patch` from bash/PowerShell, **bypassing the Python gate
entirely** — `curl \| sh` still wrote a Claude Code `PreToolUse` hook
regardless of `HEADROOM_RTK` |
| `wrap.py` `_setup_context_tool_for_agent` | **`wrap openhands` was
broken by default**: `rtk_required=True` met a gate returning `None` →
`SystemExit(1)`. Invisible because all 8 openhands tests patched
`_ensure_rtk_binary` to a fake path |
| `proxy/helpers.py`, `subscription/tracker.py` | Proxy shelled out to
`rtk gain` from `/stats`, the dashboard and `headroom perf`; the tracker
polled it per contribution (`_RTK_WIRING_DEFAULT = "enabled"`) |
| No cleanup path | Nothing removed artifacts an earlier default had
installed, so a machine that once ran the old default kept rtk in the
loop forever (#1669, #1955) |

Also worth noting: the rtk binary download had **no SHA or signature
verification** — only `rtk --version` as a smoke test.

## Type of Change

- [x] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [x] Breaking change (fix or feature that would cause existing
functionality to change)
- [ ] Documentation update
- [ ] Performance improvement
- [x] Code refactoring (no functional changes)

## Changes Made

**Removed** — `headroom/rtk/` and `headroom/lean_ctx/` packages,
`headroom/cli/wrap_rtk_metrics.py`, `_selected_context_tool` /
`_setup_context_tool_for_agent` / `_VALID_CONTEXT_TOOLS`, the `--rtk` /
`--no-rtk` / `--no-project-rtk` / `--keep-rtk` flags across all 18 wrap
subcommands, `HEADROOM_RTK*`, the proxy-side `rtk gain` polling, the
dashboard CLI-filtering panel (rows + all 8 `cliFiltering*` Alpine
getters), `paths.rtk_path()` / `lean_ctx_path()`, the SDK path helpers,
`benchmarks/rtk_loop_learn_eval.py`, and the `headroom/rtk/**` CI path
filters.

**Fails loudly, not silently** — `--context-tool` / `--no-context-tool`
/ `HEADROOM_CONTEXT_TOOL` are kept solely to error out. They live in
shell profiles, aliases and CI jobs, and accepting them as a no-op would
read as Headroom having quietly stopped working. The installers reject
them too, which matters more than it looks: their arg parsers forward
the first unknown flag **and everything after it** to the wrapped tool,
so a leftover `--no-rtk` would have silently swallowed a following
`--port` and then been ignored downstream.

**New `headroom/context_tool_cleanup.py`** — deleting the code cannot
help a machine that already ran the old default, since the hooks,
binaries and injected guidance are durable on disk.
`purge_context_tool_artifacts()` runs once per `wrap`/`unwrap` and
removes the registered hook entries, the generated hook scripts, the
Headroom-managed `~/.local/bin` symlinks, the vendored
`~/.headroom/bin/{rtk,lean-ctx}` binaries, the `lean-ctx` MCP server
entry and the marker-fenced instruction blocks. Deliberately
conservative: idempotent, **skips** a malformed config rather than
overwriting it, and only unlinks a symlink resolving inside Headroom's
own bin dir so a user's own build is untouched. It reports on
**stderr**, because `wrap/unwrap openclaw --prepare-only` emit
machine-readable JSON on stdout as their entire contract. Skipped for
`wrap selfheal` (runs from a SessionStart hook; must not race Claude
Code's writer for `~/.claude.json`) and for `--help`, which must stay
read-only.

**Client-config hardening** (discovered while investigating a "corrupted
Serena settings file" report) — `wrap.py` reset a settings file to `{}`
when an existing file would not parse, then wrote that back. One
hand-edited typo or a transient `EACCES`/`EINTR` on a valid file
destroyed the user's `permissions`, `env` and `hooks`, on **every
`headroom wrap claude`**. It now refuses to write. Separately,
`fsutil.write_text` is now atomic (temp file + `fsync` + `os.replace`),
fixing all 14 non-atomic client-config writes at once; it follows
symlinks rather than replacing them (dotfile managers) and preserves an
existing file's mode.

**Deliberately kept** — `rtk` stays in the wrapper-peel list in
`transforms/content_router.py`. It sits beside `sudo`/`env`/`timeout` as
shell-command grammar, so `rtk cat f` is still classified as a file read
for anyone running their own rtk install, which the purge intentionally
leaves alone.

Repo-wide grep for 14 removed symbols (`headroom.rtk`,
`headroom.lean_ctx`, `_ensure_rtk_binary`, `_selected_context_tool`,
`_get_context_tool_stats`, `rtk_path`, `lean_ctx_path`,
`wrap_rtk_metrics`, `HEADROOM_RTK`, `cli_tokens_avoided`,
`tokens_saved_rtk`, …) across `*.py`, `*.ts`, `*.sh`, `*.ps1`, `*.yml`,
`*.html`: **zero hits**.

Notable test changes: `test_wrap_openhands.py` no longer patches
`_ensure_rtk_binary` and asserts `wrap openhands --prepare-only` exits 0
unpatched — the regression that was previously masked.
`test_wrap_continue.py` and `test_wrap_hintfile_agents.py` were removed
(every test drove RTK instruction injection). A new
`test_subscription_tracker.py::test_load_state_written_before_cli_context_tools_were_removed`
proves a pre-removal `subscription_state.json` still loads.

## Real Behavior Proof

- **Environment:** macOS 15.4 (darwin 25.4.0), Python 3.12.6, Headroom @
this branch, real `~/.headroom` and `~/.claude` on the dev machine.
- **Exact command / steps and observed result:**

```text
# 1. Retired flag fails loudly instead of silently no-op'ing
$ headroom wrap codex --prepare-only --context-tool rtk
Error: CLI context tools (rtk, lean-ctx) have been removed from Headroom: they
rewrote shell commands through a third-party binary Headroom no longer manages.
Drop --context-tool / --no-context-tool and unset HEADROOM_CONTEXT_TOOL;
`headroom wrap` uninstalls what they left behind on first run.

$ HEADROOM_CONTEXT_TOOL=lean-ctx headroom wrap codex --prepare-only
Error: CLI context tools (rtk, lean-ctx) have been removed from Headroom: ...

# 2. install.sh rejects the retired flags (extracted parse_wrap_args harness)

$ bash -n scripts/install.sh   # syntax OK

# 3. Purge ran against the real machine, which had all the orphaned artifacts
$ python -c "from headroom.context_tool_cleanup import purge_context_tool_artifacts; ..."
  removed ~/.headroom/bin/lean-ctx        (51 MB)
  removed ~/.headroom/bin/rtk             (7.7 MB)
  removed ~/.local/bin/rtk                (symlink into ~/.headroom/bin)
  removed ~/.claude/hooks/rtk-rewrite.sh
  removed 8 lean-ctx-* hook scripts
# ~/.claude.json afterwards: 90 top-level keys, 19 projects, mcpServers unchanged
# → ~59 MB reclaimed, no unrelated key touched

# 4. stdout stays machine-readable while the purge reports (planted a fake artifact)
$ headroom wrap openclaw --prepare-only --gateway-provider-id codex >out 2>err
$ cat out
{"enabled":true,"config":{"proxyPort":8787,...}}     # parses as JSON
$ cat err
Retired CLI context tool cleanup: removed /Users/tcms/.headroom/bin/rtk

# 5. --help is inert (planted artifact survives), a real run purges

$ headroom wrap openclaw --prepare-only → purged: CORRECT

# 6. MCP purge dry-run against a copy of the real 82 KB ~/.claude.json
top-level keys 90 -> 90;  projects 19 -> 19;  LOST keys: none
all content outside mcpServers byte-identical: True
```

Dashboard rendered via the Playwright test after the panel removal:
"Token Savings" shows only `Proxy 0 (0.0%)` / `Of total wire: 36.86%`,
and "Token Usage" reads Before Compression → Proxy Removed → After
Compression with no "Filtered (this session)" row. Nothing below the
removed panel broke.

- **Not tested:** Windows and Linux (macOS only) — `install.ps1` is
verified by brace-balance and inspection, not executed, since no `pwsh`
is available locally. The wrap e2e suite (`e2e/wrap/run.py`) was updated
but not run; it needs the Docker e2e image. `serena project index`
interaction is exercised in the stacked base PR.

## Additional Notes

**Stacked on #2676** (`tejas/serena-config-bootstrap`) — please merge
that first; this PR's base should then be retargeted to `main`, or it
will read as containing that fix too.

**Breaking-change migration for users:**
- Drop `--rtk`, `--no-rtk`, `--no-project-rtk`, `--keep-rtk`,
`--context-tool`, `--no-context-tool` from any alias, script or CI job,
and unset `HEADROOM_RTK*` / `HEADROOM_CONTEXT_TOOL`. They now error
rather than being ignored, so the failure is immediate and
self-explaining.
- Previously-installed artifacts are purged automatically on the next
`wrap`/`unwrap`; no manual cleanup needed.
- `headroom perf --json` no longer carries a `cli_filtering` key, and
`/stats` no longer returns a `context_tool` section.

**Docs:** `docs/rtk-architecture.md` deleted; RTK/lean-ctx removed from
`README.md`,
`docs/content/docs/{configuration,opencode,grok-build,docker-install,filesystem-contract}.mdx`,
`docs/observability.md` and the matching `wiki/` pages.
`REALIGNMENT/09-phase-G-rtk-observability.md` is marked SUPERSEDED
rather than deleted, to keep the planning record.

**Follow-ups not in scope:** `_emit_wrap_interrupted` was deleted as
dead code — its only caller was the `except KeyboardInterrupt` guarding
the binary download, so with no download there is nothing slow left to
interrupt.

Clarify uv tool install path on macOS (#1196)
## Description

Clarifies the recommended install path for the Headroom CLI on macOS
Apple Silicon and Linux. The docs now prefer `uv tool install --python
3.13 "headroom-ai[all]"` for host-level CLI use, keep `pip install`
scoped to Python project environments, and call out absolute executable
paths for MCP clients that do not inherit interactive shell `PATH`.

## Type of Change

- [ ] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [x] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)

## Changes Made

- Added `uv tool install --python 3.13` guidance to the README, docs
install page, quickstarts, and wiki install pages.
- Documented `uv tool update-shell` for shells that cannot find the
installed `headroom` command.
- Clarified absolute MCP server command paths for clients that do not
inherit the interactive shell `PATH`.
- Pointed Intel macOS users at the Docker-native install path until
native wheel support lands.

## Testing

Describe the tests you ran to verify your changes:

- [ ] Unit tests pass (`pytest`) - not run; docs-only change.
- [ ] Linting passes (`ruff check .`) - not run; docs-only change.
- [ ] Type checking passes (`mypy headroom`) - not run; docs-only
change.
- [ ] New tests added for new functionality - not applicable.
- [x] Manual testing performed
- [x] `git diff --check upstream/main...HEAD`

## Real Behavior Proof

```bash
$ git diff --check upstream/main...HEAD
# exits 0; no whitespace errors
```

`npm --prefix docs run types:check` was also attempted. It regenerated
MDX and route types successfully, then failed in existing docs app code
because `@/lib/...` imports cannot resolve from files such as
`app/(home)/layout.tsx`, `app/api/search/route.ts`, and
`components/button.tsx`. This PR only changes `README.md`,
`docs/content/docs/installation.mdx`,
`docs/content/docs/quickstart.mdx`, and `wiki/*.md` files.

## Review Readiness

- [x] Draft PR; docs wording and install-path accuracy are ready for
review.
- [x] No code or runtime files changed.
- [x] Known docs type-check blocker is documented above.

## Test Output

```bash

feat(cli): add headroom inspect to view original vs compressed content (#1595)
## Description

Headroom exposes plenty of *quantitative* compression telemetry (token
counts, ratios, `headroom perf`, `/metrics`) but no way to actually
**see what the compressor changed** in the content. That makes it hard
to trust compression or debug a quality regression ("did it drop
something I cared about?").

This adds a `headroom inspect` command (the issue's Option 1). It reads
the proxy's existing loopback `/transformations/feed` endpoint — which
already carries the pre/post-compression message snapshots when the
proxy runs with `--log-messages` — and renders, per request, the
original vs compressed content for each message with the changed
segments highlighted. No new dependencies (stdlib `difflib`).

```
headroom inspect                 # inspect the most recent request
headroom inspect --last 5        # the 5 most recent
headroom inspect --full          # include unchanged messages
headroom inspect --format json   # raw feed for offline tooling
```

Per request it shows the model, per-request token counts + savings, the
transforms applied, and a colorized unified diff of each changed message
(red = removed, green = added). Clear errors when no proxy is reachable
or when the proxy wasn't started with `--log-messages`.

Side-by-side / interactive rendering (the fuller form of Option 1) can
follow as a polish pass; this lands the core "see what changed"
capability on data Headroom already captures.

Closes #1267

## Type of Change

- [x] New feature (non-breaking change that adds functionality)

## Changes Made

- `headroom/cli/inspect.py`: new `inspect` command +
content-flattening/diff-render helpers.
- `headroom/cli/__init__.py`, `headroom/cli/main.py`: register the
command.
- `tests/test_cli_inspect.py`: unit tests (content extraction, the
no-proxy / no-`--log-messages` / empty-feed paths, text render, json
output).
- `wiki/cli.md`: document the command + options.

## Testing

- [x] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check`)
- [x] New tests added

### Test Output

```text
$ pytest tests/test_cli_inspect.py -q
7 passed

$ ruff check headroom/cli/ tests/test_cli_inspect.py
All checks passed!
```

## Real Behavior Proof

- Environment: repo main @ HEAD, local venv
- Exact command / steps: invoked the `inspect` command against a mocked
`/transformations/feed` payload (one request, a user message with a line
removed by SmartCrusher).
- Observed result: header shows `req-1 gpt-4o`, `tokens 100 → 40 (saved
60, 60.0%)`, `transforms: SmartCrusher`, and a unified diff with the
removed line on the original side; no-proxy and missing-`--log-messages`
cases raise actionable errors; `--format json` emits the raw feed.
- Not tested: live end-to-end against a real proxy with `--log-messages`
(the data source — the feed endpoint — is exercised via the mocked
payload that mirrors its shape).

fix(proxy): dedupe Codex WS request logging for accurate mixed-provider dashboards (#2189)
## Description

Running Claude Code (Anthropic) and Codex (OpenAI) against the **same**
Headroom proxy instance on one port produced incorrect, unstable
dashboard data. The proxy core is provider-isolated and
multi-provider-safe by design; the defect was in the observability
layer. The Codex `/v1/responses` **WebSocket** handler was the only path
in the proxy that wrote to the request logger by hand instead of through
the unified `emit_request_outcome` funnel, and it did so twice per
session close: the per-turn funnel record plus an unconditional
cumulative session-summary `RequestLog`. This PR removes the duplicate
summary log so Codex WS emits exactly one request log per turn, matching
the HTTP provider paths.

## Type of Change

- [x] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [ ] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)

## Changes Made

- Dropped the duplicate cumulative session-summary `RequestLog` in the
Codex WS handler while preserving the per-turn `emit_request_outcome`
path.
- Preserved gated `request_messages` and `turn_id` on residual outcomes
so dashboard telemetry keeps the useful attribution without
double-counting tokens.
- Ensured explicit `--anyllm-provider` wins over a leaked
`HEADROOM_ANYLLM_PROVIDER` environment variable.
- Registered retry delay settings that had drifted out of the settings
registry.
- Hardened tests against developer-shell `HEADROOM_*` /
`ANTHROPIC_CUSTOM_HEADERS` leakage and stabilized several focused
proxy/wrap test fixtures.

## Testing

- [x] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check .`)
- [ ] Type checking passes (`mypy headroom`)
- [x] New tests added for new functionality
- [x] Manual testing performed

## Real Behavior Proof

- Environment: macOS (Darwin 25.4.0), Python 3.13.14, pytest 9.0.3, ruff
via project venv, branch `fix/multi-provider-runtime`.
- Exact command / steps: Ran the full test suite without pytest cache
provider and Ruff on all touched files; used `git stash` to confirm the
stale fake-config failures pre-existed this change.
- Observed result: Full suite passed with no failures; Ruff passed;
Codex WS now routes end-of-session logging through
`emit_request_outcome`, emitting one request log per turn with the same
accounting model as Anthropic HTTP turns.
- Not tested: Live simultaneous Claude + Codex dashboard run. `mypy
headroom` was not run to completion; a scoped run reported one
pre-existing `settings_store.py:470` coercion error outside this diff.

## Additional Notes

- The proxy's multi-provider routing, header/auth isolation, and
per-model cache keying are already correct and unchanged here; only the
WS observability write path was double-counting.

docs(proxy): correct --code-aware default to disabled (#1710)
## Description

The wiki proxy page (`wiki/proxy.md`, which feeds the published docs
site) claimed `--code-aware` defaults to **true**. The CLI deliberately
defaults it to **disabled**: `headroom/cli/proxy.py` resolves the paired
flag to off unless `--code-aware` is passed or
`HEADROOM_CODE_AWARE_ENABLED` is truthy, and the Click help text plus
`docs/content/docs/proxy.mdx` and `wiki/cli.md` already document it as
disabled. This PR aligns the one remaining stale table row and collapses
the self-contradictory separate `--no-code-aware` row into a single
paired-flag entry, matching the style used in
`docs/content/docs/proxy.mdx`.

Fixes #1700

## Type of Change

- [ ] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [x] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)

## Changes Made

- `wiki/proxy.md`: replaced the two flag-table rows claiming
`--code-aware` default `true` / `--no-code-aware` default `false` with
one `--code-aware` / `--no-code-aware` row documenting the actual
default (`disabled`), the `headroom-ai[code]` requirement, and the
`HEADROOM_CODE_AWARE_ENABLED=1` env opt-in.

## Testing

- [ ] Unit tests pass (`pytest`)
- [ ] Linting passes (`ruff check .`)
- [ ] Type checking passes (`mypy headroom`)
- [ ] New tests added for new functionality
- [x] Manual testing performed

### Test Output

```text
$ python -c "
from click.testing import CliRunner
from headroom.cli.proxy import proxy
r = CliRunner().invoke(proxy, ['--help'])
print([l.strip() for l in r.output.splitlines() if 'code-aware' in l][0])
"
--code-aware / --no-code-aware  Enable/disable AST-based code compression.

$ grep -n "code-aware" wiki/proxy.md
77:| `--code-aware` / `--no-code-aware` | disabled | Enable or disable AST-based code compression. Requires `headroom-ai[code]` (env: HEADROOM_CODE_AWARE_ENABLED=1 to enable) |
```

## Real Behavior Proof

- Environment: Windows 11, local checkout at `upstream/main` (9fbd47ba),
Python 3.13.
- Exact command / steps: `headroom proxy --help` (via Click test runner)
to confirm the CLI help says "Default: disabled"; inspected
`headroom/cli/proxy.py` flag resolution (explicit flag →
`HEADROOM_CODE_AWARE_ENABLED` → off); `grep -rn "code.aware" wiki/
docs/` to find every doc stating a default.
- Observed result: CLI default is disabled;
`docs/content/docs/proxy.mdx:61` and `wiki/cli.md:255-256` already say
disabled/off; only `wiki/proxy.md:77-78` claimed true. After the change
the table matches actual behavior.
- Not tested: rendered docs-site build (content-only table edit).

fix: skip Magika backend on x86 CPUs without AVX2 (#1162)
## Description

Adds a narrow runtime AVX2 guard before initializing the Magika/ONNX
Runtime detector on x86/x86_64. On x86/x86_64 CPUs without AVX2,
Headroom falls back to existing non-Magika detection tiers instead of
crashing during ONNX Runtime initialization. AVX2-capable systems retain
existing behavior.

Refs #1005

## Type of Change

- [x] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [x] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)

## Changes Made

- Adds a Magika/ONNX Runtime CPU support guard before `Session::new()`.
- Returns a normal Magika init error on x86/x86_64 hosts without AVX2,
allowing the existing detection chain to fall through to non-Magika
tiers.
- Keeps AVX2-capable x86/x86_64 behavior unchanged.
- Does not apply the x86-specific AVX2 gate on non-x86 targets.
- Adds CPU-aware Rust tests and a short troubleshooting note.

## Testing

- [ ] Unit tests pass (`pytest`)
- [ ] Linting passes (`ruff check .`)
- [ ] Type checking passes (`mypy headroom`)
- [x] New tests added for new functionality
- [x] Manual testing performed

### Test Output

```text
$ cargo test -p headroom-core --lib --locked
833 passed; 0 failed; 1 ignored

$ cargo test --workspace --locked
passed

$ cargo clippy -p headroom-core --locked -- -D warnings
clean
```

## Real Behavior Proof

- Environment: x86_64 Linux host with AVX but no AVX2 (Intel Xeon
E5-2697 v2 on Proxmox), local build from this branch.
- Exact command / steps: `python -X faulthandler -c 'from headroom._core
import detect_content_type; print(detect_content_type("hello world"))'`
- Observed result: before — process exited with `Fatal Python error:
Illegal instruction`; after — command completed successfully returning
`DetectionResult(content_type="text", ...)`, and full `cargo test -p
headroom-core --lib --locked` passed with 833/0/1.
- Not tested: generic no-AVX CPUs, alternate ONNX Runtime builds,
non-x86 platforms.

## Screenshots (if applicable)

N/A

## Additional Notes

This partially addresses #1005 by handling one concrete native crash
class: the Magika detector initializes ONNX Runtime through ort/ort-sys,
whose precompiled runtime can contain AVX2-family instructions. On
AVX-only x86_64 hosts, that initialization can SIGILL before Headroom
can fall back.

Scope:

- This does not introduce generic no-AVX wheels.
- This does not redesign Rust-core packaging.
- This does not disable the Rust core globally.
- This only prevents the Magika/ONNX detector tier from loading on
x86/x86_64 CPUs where AVX2 is unavailable.
- Non-Magika detection tiers continue to run.
- On non-x86 targets, this x86-specific AVX2 gate is not applied.

Changelog omitted: small native detector fallback fix with no public API
change.

docs: sync README + benchmarks with code (drop retired IntelligentContext/RollingWindow) (#1545)
## Description

Sync the docs with the code after the live-zone realignment. The
`IntelligentContextManager` (ICM), `RollingWindow`, and scoring modules
were deleted in PR #350 (May 2026), but the README and benchmark
docstrings still advertised them as live, and an example still imported
the deleted module (broken on run). This fixes the README + benchmarks
and removes the dead example.

I validated the README against the code with three parallel
static-analysis sub-agents (features/architecture,
CLI/extras/wrap-matrix, public API/integrations). Most of the README
checked out accurate; only the items below were stale/wrong.

Closes #

## Type of Change

- [ ] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [x] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)

## Changes Made

- README: removed the `IntelligentContext` bullet and
`IntelligentContext / RollingWindow` from the transforms list (both
deleted in PR #350).
- README: standardized `Kompress-base` -> `Kompress-v2-base` to match
the HF model id `chopratejas/kompress-v2-base` and the existing badges
(diagram re-aligned).
- README: corrected the CodeCompressor language list to match the
`CodeLanguage` enum (added TS, C, Perl).
- README: softened the unanchored "6 algorithms" tagline to
"content-aware compressors".
- README: Cortex Code is library-mode only — there is no `headroom wrap
cortex`, so the compatibility-matrix row no longer shows a wrap
checkmark.
- Deleted `examples/test_intelligent_context_toin_ccr.py` — it imported
the deleted `IntelligentContextManager` (ImportError on run) and is
unreferenced.
- Removed stale `RollingWindow` mentions from benchmark
docstrings/comments (`benchmarks/__init__.py`, `bench_transforms.py`,
`bench_latency.py`, `scenarios/conversations.py`); the accurate PR-B1
retirement comment is kept.

## Testing

- [ ] Unit tests pass (`pytest`) — N/A, docs/docstring + example
deletion only
- [x] Linting passes — `ruff check` clean on all changed benchmark files
- [ ] Type checking passes — N/A (no type-relevant changes)
- [ ] New tests added — N/A
- [x] Manual testing performed — see Real Behavior Proof

### Test Output

```text
$ ruff check benchmarks/__init__.py benchmarks/bench_transforms.py benchmarks/bench_latency.py benchmarks/scenarios/conversations.py
All checks passed!

# stale refs remaining in README/benchmarks (excluding accurate retirement notes):
$ grep -rn "IntelligentContext|RollingWindow|Kompress-base" README.md benchmarks/ | grep -v retire
(only benchmarks/bench_transforms.py:362 — the accurate PR-B1 retirement comment)

# deleted example is unreferenced anywhere:
$ grep -rn "test_intelligent_context_toin_ccr" --include=*.md --include=*.yml --include=*.py .
(no hits)
```

## Real Behavior Proof

- Environment: macOS (darwin, arm64), Python 3.12 `.venv`, ruff 0.14.x,
repo at branch `docs/sync-readme-with-code` off latest `main`.
- Exact command / steps: (1) three parallel sub-agents
grep/Read-validated README claims vs `headroom/`, `pyproject.toml`,
`sdk/typescript/`; (2) directly verified each flagged mismatch
(`CodeLanguage` enum, `HF_MODEL_ID`, absence of
`IntelligentContext`/`RollingWindow` classes); (3) confirmed the example
imports a deleted module and is unreferenced; (4) `ruff check` on
changed benchmark files; (5) re-grepped README + benchmarks for any
remaining stale refs.
- Observed result: README and benchmark docstrings now match the code;
the only surviving `RollingWindow` string is the accurate retirement
comment; the broken example is removed; ruff passes; the ASCII
architecture diagram still aligns after the `Kompress-v2-base` rename.
- Not tested: rendering of the README on GitHub/PyPI (text-only change);
the separate `docs/content/` and `wiki/` doc sets (see Additional Notes
— out of scope for this PR).

## Additional Notes

**Larger related finding (NOT in this PR):** the published docs site
(`docs/content/docs/*.mdx`) and the `wiki/*.md` set still document
`IntelligentContextManager`, `RollingWindow`, `RollingWindowConfig`,
`IntelligentContextConfig`, and `ScoringWeights` as live API — with
`from headroom import RollingWindow` / `from headroom.transforms import
IntelligentContextManager` code examples that would `ImportError`. It is
half-migrated (a couple of `.mdx` files already note "removed in 0.9.x"
while neighbors still teach it as current). This is ~15 files and the
fixes require rewriting examples to the live-zone model, not just
deletions — recommended as a focused follow-up PR rather than bundling
it here.

fix(ccr): make headroom_retrieve a hash-only full-content lookup (#1532)
The optional `query` parameter on headroom_retrieve routed retrieval
through CompressionStore.search(), which BM25-scored the items inside a
single cached blob and dropped everything below a 0.3 relevance floor.
On small per-blob corpora with conversational queries this returned an
empty result the large majority of the time, so the LLM saw "nothing
found" for content that was actually present — pushing users to turn
compression off entirely.

Retrieval is fundamentally a hash lookup (this already matches the Rust
proxy's CCR store, which is put/get only — "no BM25 search"). Remove the
query/search path end to end and always return the full original
content:

Core (Python proxy):
- tool schemas (anthropic/openai/google) drop the `query` property
- parse_tool_call returns the hash (str | None) instead of (hash, query)
- response handler, proxy POST/GET/tool-call handlers, the MCP retrieve
tool, and the streaming feedback recorders retrieve by hash only
- proactive context-tracker expansion always restores full content
- delete CompressionStore.search() and its BM25 machinery (the bm25
module stays — it is still used by relevance/)
- CCRToolCall.query, CCRToolResult.was_search, and
ExpansionRecommendation.expand_full/search_query are removed

Plugins (advertised a now-defunct query param to the LLM):
- hermes (Python), openclaw + opencode (TypeScript) retrieve tools drop
`query` from their schemas, signatures, request URLs, and tests

Benchmarks/docs:
- ccr_regression + adversarial benchmarks switch from store.search() to
full hash retrieval (search input-injection tests repurposed to the
hash, the only remaining input surface)
- wiki/ARCHITECTURE.md, wiki/ccr.md, docs/content/docs/ccr.mdx,
config.py and store docstrings updated to describe hash-only retrieval

Tests updated to assert full-content retrieval and guard the removed
surface; the full CCR/proxy/store/TOIN suite passes. ruff + mypy clean.

chore: remove committed node_modules + stray/internal markdown (repo hygiene) (#1528)
## Description

Repo hygiene for a public OSS project: removes committed `node_modules`,
stray/internal/draft markdown, and commercial-surface references —
keeping every real doc (the published docs site, the wiki guides, and
all component READMEs) intact. Every file was content-audited before
removal, and load-bearing files were verified against the code/CI and
kept.

Net: **1,695 files changed, +23 / −266,409** (the deletions are
dominated by a committed `node_modules` tree).

Closes # (no tracking issue)

## Type of Change

- [ ] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [x] Documentation update
- [x] Code refactoring (no functional changes)

## Changes Made

**Removed (verified to have no code/CI dependencies):**
- `examples/vercel-ai-sdk-pr/` — 1,649 committed `node_modules` files
(zero example source); `node_modules/` added to `.gitignore`.
- `docs/spec/` (23 draft "Living Specification" files — orphaned,
`1.0.0-draft`, drifted from the code), `docs/superpowers/` (2 agent
plans), `docs/proposals/` (2 internal/commercial memos).
- 6 orphan `docs/*.md` (auth-modes, bedrock,
claude-code-vertex-headroom, cortex-code, output-token-reduction-guide,
rtk-loop-weighting).
- `PR.md` (committed PR draft), `ENTERPRISE.md`, `.github/FUNDING.yml`.

**Content scrubs:**
- Removed unreleased "Headroom Cloud" / `api.headroom.ai` / `hr_`
references from `configuration.mdx`, `wiki/configuration.md`,
`wiki/typescript-sdk.md`, `sdk/typescript/README.md` (reworded to
neutral, accurate phrasing).
- Dropped a stale "awaiting maintainer before merge" line from
`plugins/headroom-oauth2/SPEC.md`; tidied `.gitignore` comments (kept
the protective `headroom-managed/` ignore rule).
- Fixed the now-dangling links into removed files (README
nav/`output-token-reduction` link, `scripts/README`, `wiki/vertex`).

**Explicitly KEPT (load-bearing — would orphan in-code citations if
removed):**
- `.changelog.md` — consumed by `.github/workflows/release.yml` (read as
the release-notes file).
- `REALIGNMENT/`, `docs/observability.md`, `docs/rtk-architecture.md`,
`wiki/plans/`, `TESTING-copilot-subscription.md` — referenced by the
Rust core / Python / tests as design docs.

## Testing

- [ ] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check`)
- [ ] Type checking passes (`mypy`)
- [x] New tests added for new functionality
- [x] Manual testing performed

### Test Output

```text
# Docs/markdown + .gitignore only — no Python/Rust source changed, so the
# behavioral test suite is unaffected. Verified the cleanup did not orphan
# references or break the published docs site:

$ git ls-files 'docs/content/docs/*.mdx' | wc -l      # published site intact
42
$ # meta.json nav unchanged; no published page removed.

$ grep -rnI "Headroom Cloud|api.headroom.ai|'hr_" $(git ls-files '*.md' '*.mdx')
>>> none

$ # dangling refs to removed files (excl pre-existing P0/P2 spec stubs that
$ # never existed in git): none remaining.
```

## Real Behavior Proof

- Environment: macOS, local git clone of the repo (markdown/.gitignore
changes only — no runtime).
- Exact command / steps: 4 read-only content-audit agents classified
every `.md`/`.mdx` file; each removal candidate was cross-checked
against the codebase (`grep` for citations in `.rs`/`.py`/tests,
workflows, and configs); only files with no dependents were removed; the
tree was re-grepped after removal to confirm no new dangling references;
verified the published docs site page count (`git ls-files
'docs/content/docs/*.mdx' | wc -l` = 42, unchanged).
- Observed result: the 42-page published docs site and all wiki guides
are untouched; no source or workflow references a removed file;
`.changelog.md` (consumed by release.yml) and the code-cited design docs
were detected as dependencies and kept; the committed `node_modules`
tree is removed and `node_modules/` is gitignored so it can't be
re-committed; zero "Headroom Cloud"/`headroom.dev` references remain.
- Not tested: N/A — no executable code changed (only markdown, `.mdx`,
and `.gitignore`), so the behavioral test suite is unaffected.

## Additional Notes

- This branch deletes `.github/FUNDING.yml` while PR #1526 edits it —
the two will be sequenced at merge (delete wins).
- A follow-up option (not in this PR): also remove the internal design
docs that are currently cited by the code (`REALIGNMENT/`,
`docs/observability.md`, `docs/rtk-architecture.md`, `wiki/plans/`) —
that requires scrubbing ~15–20 in-code citations so nothing dangles, so
it's deliberately deferred.
- Untracked local working files (`benchmarks/hf_pilot/`,
`tools/copilot-test/`) are intentionally left out of git (not
committed).

fix(cli): harden all CLI surfaces + fix docs accuracy (#1491)
## Summary

Full CLI audit + documentation accuracy pass. All 5 commits on this
branch:

### CLI Hardening (4 commits)
- **Clean errors instead of tracebacks**: corrupt manifests, missing
Docker, malformed JSONL, bad `--profile`, invalid env-var values all now
raise `click.ClickException` with helpful messages
- **Range validation**: ~25 numeric flags across 10 files now use
`click.IntRange`/`FloatRange` — `--port 0`, `--hours -1`, `--limit 0`
etc. produce clean usage errors instead of silent wrong behavior
- **Flag combination warnings**: conflicting combos (`--no-rate-limit` +
`--rpm`, `--no-optimize` + `--target-ratio`, `--telemetry` +
`--no-telemetry`) emit yellow warnings on stderr
- **`memory --db-path` default fixed**: was resolving to
`headroom_memory.db` (wrong bare file); now uses project store
`./.headroom/memory.db` if present, else `~/.headroom/memory.db`
- **`memory list --search` + filters**: `--scope`/`--session`/`--since`
were silently ignored when `--search` was also set; now filters are
applied to search results
- **`learn --verbosity --apply` now works**: the output shaper is off by
default (`HEADROOM_OUTPUT_SHAPER`); `--apply` now hot-enables it via
`POST /admin/runtime-env` on a running proxy, or prints explicit `export
HEADROOM_OUTPUT_SHAPER=1` instructions when no proxy is running
- **`perf --hours` overflow**: `1e9` hours no longer raises
`OverflowError`; treated as "all data"
- **`evals memory --categories` invalid input**: `abc,1,2` now raises
`BadParameter` instead of a raw `ValueError` traceback

### Documentation (1 commit, 20 files)

Corrected factual errors found by 3 parallel audit agents across root
docs, wiki, and the published Fumadocs site:

**Critical (caused runtime errors or wrong behavior if followed):**
- `simulation.mdx`: `plan.transforms_applied` -> `plan.transforms`;
`plan.savings_percent` -> computed from available fields (both raised
`AttributeError`)
- `shared-context.mdx`: `import { SharedContext } from "headroom"` ->
`"headroom-ai"` (5x `ImportError`)
- `claude-code-azure-foundry.mdx`: `pip install headroom` -> `pip
install headroom-ai`
- `api-reference.mdx` + `configuration.mdx`: `from headroom import
GoogleProvider` -> `from headroom.providers import GoogleProvider`
- `ccr.mdx`: CCR TTL default 300s -> 1800s (30 min)

**Fabricated flags removed:**
- `wiki/proxy.md` + `wiki/cli.md`: `--no-intelligent-context`,
`--no-intelligent-scoring`, `--no-compress-first` (none exist); replaced
with real CCR flags
- `wiki/configuration.md`: `--no-ccr-responses`, `--no-ccr-expansion`
(none exist); replaced with real flags
- `wiki/troubleshooting.md`, `wiki/metrics.md`,
`docs/troubleshooting.mdx`: `headroom proxy --log-level debug` (flag
doesn't exist)

**Stale content corrected:**
- `llms.txt`: telemetry stated as enabled-by-default (it's opt-in); wrap
list had 5 tools (now 11)
- `README.md`: compatibility matrix added 5 missing `wrap` targets;
`unwrap`, `doctor`, `init`/`install`, savings-analytics now mentioned
- `SECURITY.md`: supported version table showed 0.2.x (current: 0.27.x)
- `wiki/learn.md`: 5 missing flags added; verbosity shaper-off behavior
documented
- `wiki/quickstart.md`: "Configuration Reference" linked to `api.md`
(wrong) -> `configuration.md`
- `CacheAlignerConfig.enabled` default corrected: `True` -> `False`
- `opencode.mdx`: `--port` default wrong ("random") -> 8787; `openai`
backend removed
- `CONTRIBUTING.md`: broken Markdown table cell fixed
- `docs/meta.json`: `claude-code-azure-foundry` added to nav (was
unreachable orphan page)
- `configuration.mdx`: SDK modes vs proxy `--mode` now clearly
distinguished

## Test plan

- [x] `python -m pytest tests/ -x -q` — 857 passed, 0 failures
- [x] 41-combination CLI smoke test (all flag combos across 8 commands)
— 0 tracebacks
- [x] `ruff check` on all modified Python files — clean
- [x] Docs changes are removals/corrections of fabricated or stale
content; no new claims introduced

fix: surface output reduction without a restart, and explain $0.00 savings on Python 3.14 (#1296)
## Description

I was running headroom through pipx on Python 3.14 and hit two issues.

The Proxy $ Saved tile was stuck at $0.00 even though tokens were
tracking fine. Pricing comes from litellm, and litellm does not install
on Python 3.14 because of a version lock, so there was just nothing to
price against. Rather than hardcode a price table that goes stale, I
added a `litellm_available` flag to `/stats` and the tile now tells you
to reinstall on 3.13 when pricing isn't there, like the output-shaper
tile already does.

The other one was Output Tokens Saved showing "—" after I turned on the
shaper. The recorder reads the learned baseline once at startup, so if
you run `learn --verbosity --apply` while the proxy is already up it
never gets picked up, and a later flush writes the empty baseline over
the one learn just saved. Now it re-reads the baseline before estimating
and before each flush, so it works without a restart.

Closes # N/A (no tracking issue)

## Type of Change

- [x] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [x] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)

## Changes Made

- `output_savings.py`: re-read the baseline from disk before estimating
and before each flush, so a baseline learned while the proxy is running
takes effect (and a re-learn with the same sample count too).
- `server.py`: expose a `litellm_available` flag on `/stats`.
- `dashboard.html`: when savings are zero and litellm is missing, point
to reinstalling on 3.13 instead of showing $0.00.
- tests and docs (`test_output_savings.py`, README, metrics, CHANGELOG).

## Testing

- [x] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check .`)
- [x] Type checking passes (`mypy headroom`)
- [x] New tests added for new functionality
- [x] Manual testing performed

### Test Output

```text
$ pytest tests/test_output_savings.py -q
34 passed, 1 warning in 0.11s
```

## Real Behavior Proof

- Environment: macOS, Python 3.13 (litellm present) and 3.14 (litellm
absent), running this branch.
- Exact command / steps: record shaped traffic, write a baseline to the
same file while the recorder is live (no restart), then estimate and
flush.
- Observed result: the recorder goes from `available: False` to
`available: True` once the baseline is written mid-run, and keeps it
after a flush. Before this it stayed `False` and the flush reset the
baseline. Raw output:
  ```text
  shaper traffic recorded, baseline not learned yet -> available: False
  learn --apply wrote baseline while proxy up; restart NOT performed
after baseline write -> available: True | method: estimated | pct: 50.3
  baseline kept after flush -> disk samples: 4
  ```
- Not tested: I did not render the tile hint in a browser, I checked the
flag on `/stats` and read the template instead.

## Additional Notes

Just a final note, ruff and mypy are clean on what I changed. The
repo-wide `ruff check .` and `mypy headroom` do report a few problems,
but they're in files I didn't touch and already exist on the base
commit, so I left them alone to keep this small. Happy to do a separate
cleanup PR.

docs: use headroom-ai package name in install commands (#1014) (#1257)
## Description

Install commands across the docs referenced the unpublished `headroom`
package instead of the published `headroom-ai`, so copy-pasted `pip
install` commands fail. This corrects them to `headroom-ai` (with
extras).

Closes #1014

## Type of Change

- [x] Documentation update

## Changes Made

- `wiki/getting-started.md`: corrected 4 `pip install headroom` commands
to `headroom-ai` (including the `[proxy]`, `[relevance]`, and `[all]`
extras).
- `docs/content/docs/claude-code-vertex.mdx`: fixed the install command
on line 37.
- `SECURITY.md`: fixed the install command on line 47.

## Testing

- [x] Manual verification

### Test Output

```text
$ rg -n "pip install headroom\b" docs wiki SECURITY.md
(no matches — all bare `headroom` install commands now use `headroom-ai`)
```

## Real Behavior Proof

- Environment: Windows 11, repo working tree on branch
fix/docs-1014-headroom-ai-pkg
- Exact command / steps: Grepped the docs tree for `pip install
headroom` before and after the edits.
- Observed result: Before, several occurrences referenced the
unpublished `headroom`; after, only `headroom-ai` remains (the spec doc
reference is intentionally left untouched).
- Not tested: Did not run a live `pip install headroom-ai` against PyPI
in CI.

feat(proxy): add request timeout config (#738)
## Description

Add --request-timeout-seconds CLI flag and HEADROOM_REQUEST_TIMEOUT
environment variable to the headroom proxy command, allowing users to
configure the upstream request timeout (default: 300s). This is useful
for slow providers such as local LLM servers (Ollama, vLLM, llama.cpp)
where the default timeout may be insufficient.

Fixes #737

## Type of Change

- [ ] Bug fix (non-breaking change that fixes an issue)
- [x] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [ ] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)

## Changes Made

- Added --request-timeout-seconds option to the proxy command with
HEADROOM_REQUEST_TIMEOUT envvar support
- Passed request_timeout_seconds (default: 300s when not specified)
- Added tests for both CLI flag and environment variable paths

## Testing

- [x] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check .`)
- [x] Type checking passes (`mypy headroom`)
- [x] New tests added for new functionality
- [x] Manual testing performed

### Test Output

```text
$  pytest tests/test_cli_proxy_env.py -q
45 passed in 3.46s

$  mypy headroom
Success: no issues found in 356 source files

$  ruff check .

fix(telemetry): switch anonymous telemetry to opt-in (off by default) (#1223)
## Description

Anonymous usage telemetry was **on by default** (opt-out). This flips it
to **opt-in**: nothing is collected or shipped unless the user
explicitly turns it on. Small change, but it makes "no data leaves the
proxy by default" the actual default rather than something users have to
discover and disable.

Closes # <!-- N/A: no tracking issue -->

## Type of Change

- [ ] Bug fix (non-breaking change that fixes an issue)
- [x] New feature (non-breaking change that adds functionality) — adds
`--telemetry` opt-in flag
- [x] Breaking change (fix or feature that would cause existing
functionality to change) — telemetry no longer runs unless opted in
- [x] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)

## Changes Made

- `is_telemetry_enabled()` is now **fail-closed**: only explicit
on-values (`on`/`true`/`1`/`yes`/`enable`/`enabled`) enable telemetry;
unset, empty, or unrecognized values stay disabled. This single
predicate gates both the Supabase beacon and the local `/v1/telemetry`
collector.
- Added `--telemetry` opt-in flag to `headroom proxy` and `headroom
install apply`; kept `--no-telemetry` and `HEADROOM_TELEMETRY=off` for
back-compat. If both are passed, opt-out wins.
- Install manifests now write `HEADROOM_TELEMETRY` explicitly
(`on`/`off`) plus the matching flag, so generated systemd/docker/launchd
deployments are unambiguous and don't rely on the runtime default.
- Startup banner and proxy log show `DISABLED` by default and surface
how to opt in.
- Updated tests for opt-in defaults; added coverage for the default-off
banner, the `--telemetry` flag, and the explicit-on manifest path.
- Updated docs
(proxy/configuration/installation/benchmarks/community-savings mdx, spec
011/015, wiki proxy/cli/benchmarks/metrics) and `CHANGELOG.md`.

## Testing

- [x] Unit tests pass (`pytest`) — targeted telemetry + install-planner
suites
- [x] Linting passes (`ruff check`)
- [x] Type checking passes (`mypy`)
- [x] New tests added for new functionality
- [x] Manual testing performed

### Test Output

```text
$ python -m pytest tests/test_telemetry_warning.py tests/test_telemetry.py tests/test_install/test_planner.py -q
81 passed

$ ruff check <changed source + test files>
All checks passed!

       headroom/install/planner.py headroom/proxy/server.py
Success: no issues found in 5 source files
```

## Real Behavior Proof

- **Environment:** macOS (darwin 25.4.0), project `.venv`, `headroom`
CLI.
- **Exact command / steps:**
  ```
$ python -c "import os; from headroom.telemetry.beacon import
is_telemetry_enabled; \
os.environ.pop('HEADROOM_TELEMETRY', None); print('unset ->',
is_telemetry_enabled()); \
[ (os.environ.__setitem__('HEADROOM_TELEMETRY', v), print(repr(v), '->',
is_telemetry_enabled())) \
        for v in ['on','TRUE','1','yes','off','0','garbage',''] ]"

  $ headroom proxy --help        | grep -i telemetry
  $ headroom install apply --help | grep -i telemetry
  ```
- **Observed result:**
  ```
  unset      -> False      # off by default
  'on'       -> True       'TRUE' -> True   '1' -> True   'yes' -> True
  'off'      -> False      '0' -> False
  'garbage'  -> False      ''  -> False     # fail-closed

proxy: --telemetry Opt in to anonymous usage telemetry — off by default
(env: HEADROOM_TELEMETRY=on)
--no-telemetry Force anonymous usage telemetry off (already the default;
env: HEADROOM_TELEMETRY=off)
install: --telemetry Opt in to anonymous telemetry in the runtime (off
by default).
--no-telemetry Force anonymous telemetry off in the runtime (already the
default).
  ```
- **Not tested:** live Supabase beacon network round-trip (no opt-in
network call was made); full `pytest` suite was not run — only the
telemetry + install-planner targeted suites.

## Additional Notes

- "Breaking change" is checked because the default behavior changes
(telemetry stops running unless opted in). It is **not** an API break —
`--no-telemetry` and `HEADROOM_TELEMETRY=off` still work, so existing
opt-out configs are unaffected.
- No tracking issue, so `Closes #` is left N/A.

docs(vertex): Claude Code + Vertex via Headroom guide (validated) (#1180)
## Description

Documents the **validated** way to run **Claude Code** against **Claude
models on Google Vertex AI** with **Headroom compressing the context**.
Corrects the prior review's assumption that the "Vertex-mode redirect"
approach would work — Claude Code's client-side `probeVertexModel`
blocks it — and documents the working **Anthropic-mode + LiteLLM
`vertex_ai`** path, verified end-to-end against live Vertex quota (~22%
context compression observed).

Closes # <!-- n/a -->

## Type of Change

- [ ] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [x] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)

## Changes Made

- **`docs/claude-code-vertex-headroom.md`** (new) — copy-paste runbook:
prerequisites (GCP ADC, `google-cloud-aiplatform`, Vertex quota),
two-terminal setup (proxy `--backend litellm-vertex_ai --region <loc>
--code-aware`; Claude Code in normal Anthropic mode via
`ANTHROPIC_BASE_URL`), verification, a troubleshooting table, and a
section on what `--code-aware` does and what it never touches (local
files / protected `Read`/`Glob`/`Grep`/`Write`/`Edit` output).
- **`wiki/vertex.md`** — new "Claude Code with Headroom compression"
section pointing at the runbook, with the two ⚠️ caveats (Vertex-mode
probe rejects custom URLs; `vertexai` dep + `--code-aware` required).
- **`docs/proposals/vertex-claude-compression-review.md`** — corrected
TL;DR: Setup A is blocked by Claude Code's probe; Setup B is the
validated path.

## Testing

- [ ] Unit tests pass (`pytest`) — **N/A (docs-only, no code changed)**
- [ ] Linting passes (`ruff check .`) — **N/A (no Python changed)**
- [ ] Type checking passes (`mypy headroom`) — **N/A (no Python
changed)**
- [ ] New tests added for new functionality — **N/A (docs)**
- [x] Manual testing performed (live Vertex validation — see below)

### Test Output

```text
# 1) Direct Vertex quota check (global)
POST .../locations/global/publishers/anthropic/models/claude-sonnet-4-6:rawPredict

# 4) Compressors loaded (GET /debug/warmup)
{'kompress':'loaded', 'code_aware':'loaded', 'tree_sitter':'loaded', 'smart_crusher':'loaded'}
```

## Real Behavior Proof

- **Environment:** macOS (arm64); Claude Code 2.1.181; Headroom 0.27.0;
venv Python 3.12; LiteLLM `vertex_ai` via `google-cloud-aiplatform`
1.158.0; GCP project `eternal-sunset-495505-t0`; Vertex location
`global`; model `claude-sonnet-4-6` (only model with quota on this
project); auth via `gcloud auth application-default login` (ADC).
- **Exact command / steps:** the two-terminal setup in
`docs/claude-code-vertex-headroom.md` — proxy `headroom proxy --port
8787 --backend litellm-vertex_ai --region global --code-aware`; client
`ANTHROPIC_BASE_URL=http://127.0.0.1:8787` +
`ANTHROPIC_MODEL=claude-sonnet-4-6` in normal mode (no
`CLAUDE_CODE_USE_VERTEX`).
- **Observed result:** Claude Code answered via Vertex (`modelUsage:
claude-sonnet-4-6`); ~22% context compression
(`router:tool_result:mixed`) on a code-heavy request forwarded to Vertex
`global`; all compressors loaded.
- **Not tested:** cumulative savings over long multi-turn sessions;
non-global regions (no quota on this project); Opus 4.8 (not enabled in
this project — 404); automated tests for the LiteLLM-vertex path (still
absent — pre-existing gap).

- **Follow-ups:** optional `headroom wrap claude` Vertex turnkey; add
automated tests for the LiteLLM-vertex path; consider defaulting
`--code-aware` (or warning when code content is detected but code-aware
is off), since its default-off state makes compression silently no-op on
coding sessions.

docs: document HEADROOM_BETA_HEADER_STICKY and HEADROOM_BETA_TRACKER_MAX_SESSIONS (#1060)
## Description

Documents `HEADROOM_BETA_HEADER_STICKY` and
`HEADROOM_BETA_TRACKER_MAX_SESSIONS` — two env vars that exist in source
and tests but are absent from all `.md` / `.mdx` docs. Adds a **Session
Beta Header Tracking** section explaining the `SessionBetaTracker`
behavior, its prefix-cache rationale, and the operator trade-off.

An operator debugging a beta-header-related upstream rejection cannot
discover the knob or the off-switch without reading source.

Closes #1059

## Type of Change

- [ ] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [x] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)

## Changes Made

**`wiki/configuration.md`**
- Two new rows in the Environment Variables table:
`HEADROOM_BETA_HEADER_STICKY` and `HEADROOM_BETA_TRACKER_MAX_SESSIONS`
- New `## Session Beta Header Tracking` section with: what the mechanism
does, why it exists (prefix-cache stability), the operator trade-off,
and how to disable

**`docs/content/docs/configuration.mdx`**
- Same two rows added to the Environment Variables table
- Same `### Session Beta Header Tracking` section (matching heading
level)

## Testing

- [ ] Unit tests pass (`pytest`)
- [ ] Linting passes (`ruff check .` — N/A, docs-only change to
`.md`/`.mdx` files)
- [ ] Type checking passes (`mypy headroom` — N/A, docs-only)
- [ ] New tests added for new functionality — N/A, docs-only
- [x] Manual testing performed

### Test Output

```text
Manual verification: confirmed env var names, accepted values, defaults, and LRU bound match code (helpers.py:1610-1629, 1613-1614, 1820-1822). Existing tests exercise the behavior (tests/test_anthropic_beta_session_sticky.py:124).
```

## Real Behavior Proof

- Environment: Ubuntu 24.04, Python 3.12, Headroom v0.25.0, provider:
Anthropic (Claude Code via `headroom wrap`)
- Exact command / steps: `grep -ri "HEADROOM_BETA_HEADER_STICKY"
README.md CHANGELOG.md wiki/ docs/` → 0 matches before; source
inspection of helpers.py:1605-1856, anthropic.py:918-961,
prefix_tracker.py:316-335
- Observed result: env vars now documented in both wiki + docs mirrors;
behavior rationale and trade-off explained
- Not tested: end-to-end proxy run with the new docs in place (docs-only
change; behavior unchanged)

## Additional Notes

Mirrors the same dual-file pattern used in #579 (wiki + docs mdx). The
documented behavior is contractual — confirmed by
tests/test_anthropic_beta_session_sticky.py:124
(test_beta_seen_turn_1_present_in_turn_2_even_if_client_drops) and the
test module docstring naming Claude Code and Codex CLI as the targeted
clients.

docs: correct macOS troubleshooting Python floor to 3.10+ (#981)
## Description

`wiki/macos-deployment.md` told users that Headroom "Requires Python
3.9+", but the project's actual floor is Python 3.10. This corrects that
one line to 3.10+ so it matches `pyproject.toml` and every other doc.

Closes #

## Type of Change

- [x] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [x] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)

## Changes Made

- `wiki/macos-deployment.md` (troubleshooting → "Common causes"):
`Requires Python 3.9+` → `Requires Python 3.10+`.

## Testing

<!-- Check what you actually ran, then paste the real command output
below. -->

- [ ] Unit tests pass (`pytest`)
- [ ] Linting passes (`ruff check .`)
- [ ] Type checking passes (`mypy headroom`)
- [ ] New tests added for new functionality
- [x] Manual testing performed

### Test Output

```text
# Ground truth — the real Python floor:
$ grep -n 'requires-python' pyproject.toml
11:requires-python = ">=3.10"

# Every other doc already says 3.10+, and this was the only "3.9" left:
$ grep -rniE 'requires? python *3\.(9|10)' README.md docs/ wiki/ CONTRIBUTING.md
README.md: ... Requires **Python 3.10+**.
docs/content/docs/installation.mdx:16: Headroom requires **Python 3.10+** ...
docs/content/docs/installation.mdx:245: This project requires **Python 3.10+**.
wiki/index.md:405: Requires Python 3.10+.
CONTRIBUTING.md:125: - Python 3.10+. ...
wiki/macos-deployment.md:426: - Python version incompatible: Requires Python 3.10+   # fixed by this PR
```

## Real Behavior Proof

- Environment: local clone at `origin/main`; this is a
documentation-only change.
- Exact command / steps: confirmed `pyproject.toml` declares
`requires-python = ">=3.10"`; grepped all docs and found
`wiki/macos-deployment.md` was the only file claiming `3.9+`; changed
that single line to `3.10+`.
- Observed result: all Python-floor mentions across README,
`docs/content/docs/installation.mdx`, `wiki/index.md`,
`CONTRIBUTING.md`, and now `wiki/macos-deployment.md` agree on 3.10+,
matching `requires-python`.
- Not tested: N/A — single-line prose fix in a Markdown file; no code
paths, no build, no runtime behavior involved.

## Review Readiness

- [x] I have performed a self-review
- [x] This PR is ready for human review

## Checklist

- [x] My code follows the project's style guidelines
- [x] I have performed a self-review of my code
- [ ] I have commented my code, particularly in hard-to-understand areas
- [x] I have made corresponding changes to the documentation
- [x] My changes generate no new warnings
- [ ] I have added tests that prove my fix is effective or that my
feature works
- [x] New and existing unit tests pass locally with my changes
- [ ] I have updated the CHANGELOG.md if applicable

## Additional Notes

Documentation-only change, so `pytest`/`ruff`/`mypy` over the `headroom`
package are N/A — the diff contains no Python source. The fix was a
misleading minimum specifically in the version-incompatibility
troubleshooting step, where the wrong floor (3.9 vs the real 3.10) would
actively mislead a user diagnosing a Python version problem on macOS.

feat(memory): add opt-in Apple-GPU (MPS) embedding runtime (#766)
## Description

On Apple-Silicon Macs — especially fanless models like the MacBook Air
(M5) — running the proxy with memory context injection can pin the CPU
while embedding. The embedding work runs an uncapped session on the CPU,
saturating multiple cores, which starves the proxy's asyncio loop and
leads to request timeouts.

This PR adds an **opt-in** runtime that offloads the memory embedder to
the Apple GPU (MPS). Setting `HEADROOM_EMBEDDER_RUNTIME=pytorch_mps`
routes embedding through the torch `sentence-transformers` backend on
MPS instead of the default ONNX CPU embedder, moving the work off the
CPU and keeping the proxy responsive.
The default behavior is unchanged — the feature is strictly opt-in,
env-var only, and falls through to the existing default embedder
selection (with a warning) whenever MPS or the torch dependencies are
unavailable.

Fixes: N/A — no tracking issue (surfaced while running codex auto-review
through
the proxy on a fanless MacBook Air (M5)).

## Type of Change

- [ ] Bug fix (non-breaking change that fixes an issue)
- [x] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [ ] Documentation update
- [x] Performance improvement
- [ ] Code refactoring (no functional changes)

## Changes Made

- **Runtime selection** (`headroom/proxy/memory_handler.py`): read
`HEADROOM_EMBEDDER_RUNTIME`; when set to `pytorch_mps` **and** MPS is
actually available, route the memory embedder to the torch
`sentence-transformers` backend (Apple GPU).
- If MPS is unavailable or torch/sentence-transformers is not installed,
log a warning and fall through to the existing default embedder
selection (ONNX when available, else the pre-existing local
sentence-transformers fallback) — no crash. The default (env var unset)
is unchanged. Env-var only
- **MPS serialization** (`headroom/memory/adapters/embedders.py`):
`LocalEmbedder` now funnels every `encode()` through a dedicated
single-worker `ThreadPoolExecutor` when the resolved device is MPS.
torch-MPS is not thread-safe, and the existing `run_in_executor(None,
...)` dispatch would otherwise let concurrent proxy requests call MPS
from multiple threads. CPU/CUDA keep the shared default executor
(behavior unchanged). `close()` also drops the cached model so re-use
after close re-initializes cleanly.
- **Packaging** (`pyproject.toml`): new `pytorch-mps` extra (`torch` +
`sentence-transformers`), **platform-gated to macOS** (`; sys_platform
== 'darwin'`) since MPS is Apple-Silicon-only. Deliberately left out of
`[all]` (its deps already arrive via `[ml]`/`[memory]`).
- **Tests** (`tests/test_memory/test_embedder_mps_serialization.py`):
regression coverage for the serialized executor, concurrency safety (no
SIGABRT), CPU-path default behavior, and close/re-use re-initialization.
- **Docs**: `wiki/{configuration,memory,macos-deployment}.md`,
`docs/content/docs/{configuration,installation,memory}.mdx`,
`README.md`, `CHANGELOG.md`.

## Testing

- [x] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check .`)
- [x] Type checking passes (`mypy headroom`)
- [x] New tests added for new functionality
- [x] Manual testing performed (CPU-offload + concurrency profiling on
Apple Silicon)

## Additional Notes

**Why MPS (and not CoreML or a thread cap):** measured on an
Apple-Silicon Mac, the default uncapped CPU embedding session saturates
the cores; the same model on MPS runs at a fraction of the CPU (≈8x
lower sustained CPU utilization in profiling) while producing
**byte-identical embeddings** (cosine distance ≈ 0 across runtimes), so
relevance/ranking is unchanged. A CoreML execution-provider path was
evaluated and rejected: the default optimized ONNX model uses fused ops
that fall back to CPU under CoreML (no offload), and a full-precision
re-export was impractical (very low throughput + multi-GB memory). MPS
via `sentence-transformers` was the only practical GPU offload.

**Why serialization is mandatory:** torch-MPS is not thread-safe —
concurrent encode calls from a multi-worker executor abort with
`-[IOGPUMetalCommandBuffer validate]: failed assertion 'commit an
already committed command buffer'` (reproduced deterministically; a
single-worker executor resolves it).
Under concurrent load the serialized single-GPU-stream throughput meets
or exceeds the parallel CPU path while using a fraction of the cores.

**Scope / boundary:** this targets the Python **memory** embedder, which
is live on the proxy request path (memory context injection). The
Rust-backed SmartCrusher compression path is unaffected and remains
non-configurable from Python by design.

**Safety:** default behavior is unchanged (ONNX, no torch). The feature
is opt-in, env-var only, macOS-gated at the packaging layer, and
degrades gracefully (warn + the existing default embedder selection)
when MPS or the dependencies are unavailable.

feat(kompress): warn on unrecognized HEADROOM_KOMPRESS_BACKEND + document backend selection (#204)
## Summary

This PR was originally \"HEADROOM_KOMPRESS_BACKEND env + GPU/MPS
auto-detect\" (for #202). While it sat, main independently shipped the
backend-selection env var in a2ea9648 (\"fix: add Kompress backend and
thread controls\") with a richer backend set (`auto` / `onnx` /
`onnx_cpu` / `onnx_coreml` / `pytorch` / `pytorch_mps` + shorthand
aliases) and an explicit design decision to keep `auto` on the
ONNX-CPU-first path rather than auto-preferring accelerators. Rather
than re-litigate that, this PR has been rebased onto latest main and
rescoped to the two pieces main still lacks:

1. **Warn on unrecognized `HEADROOM_KOMPRESS_BACKEND` values** —
previously typos (`gpu`, `cudaa`, …) silently mapped to `auto`,
indistinguishable from the default. Now a warning names the offending
value and the accepted set; behavior still falls back to `auto`.
2. **Documentation** — the env var and its six backends/aliases were
undocumented outside the source. Added a \"Kompress backend selection\"
section to `wiki/configuration.md` and a CHANGELOG entry.

## Testing

- `pytest tests/test_transforms/test_kompress_compressor.py` — 28 passed
(includes 2 new tests: warning fires on unrecognized value; valid values
and unset stay silent)
- `ruff check` / `ruff format` clean on touched files
- No behavior change beyond the new warning, so no GPU/MPS hardware
validation is required for this scope.

feat: add Vertex AI proxy routing (#793)
## Description

Adds first-class GCP Vertex AI proxy routing for publisher REST
endpoints so Vertex requests are forwarded to a configurable regional
Vertex host instead of falling through to the generic
OpenAI/Anthropic/Gemini passthrough selection.

Fixes #792

## Type of Change

- [x] New feature (non-breaking change that adds functionality)
- [x] Documentation update

## Changes Made

- Added a `vertex` provider target with `VERTEX_TARGET_API_URL` and
`--vertex-api-url` support.
- Registered explicit Vertex publisher routes for Google
`generateContent`, `streamGenerateContent`, `countTokens` and Anthropic
publisher `rawPredict`, `streamRawPredict` passthrough.
- Added startup banner/routing output for Vertex AI.
- Added focused tests for provider target resolution, CLI/env config,
banner output, and route delegation.
- Added `wiki/vertex.md` with usage examples and Google Cloud source
links.

## Sources

- Vertex AI Gemini inference reference:
https://docs.cloud.google.com/vertex-ai/generative-ai/docs/model-reference/inference
- Google Cloud REST authentication:
https://docs.cloud.google.com/docs/authentication/rest
- Google Application Default Credentials:
https://docs.cloud.google.com/docs/authentication/application-default-credentials

## Testing

- [x] Linting passes (`python -m ruff check .`)
- [x] New tests added for new functionality
- [x] Focused unit tests pass
- [ ] Full unit suite completed locally
- [ ] Rust tests completed locally
- [ ] Type checking passes locally

## Test Output

```text
$ python -m ruff check .
All checks passed!

$ python -m pytest tests/test_provider_registry.py tests/test_provider_proxy_routes.py tests/test_cli_proxy_env.py tests/test_banner_upstream_targets.py -q
57 passed, 1 warning in 13.75s
```

Local limitations:

- `python -m pytest tests scripts/tests -q` timed out after 1 hour on
this Windows machine before completing.
- `cargo test -p headroom-proxy --test integration_vertex_raw_predict`
could not run because `cargo` is not installed on PATH in this
environment.
- The commit hook's `mypy` step fails locally on an existing Windows
`fcntl` typing issue in `headroom/subscription/tracker.py`; `ruff`,
`ruff-format`, and plugin-version hooks passed, and the commit was made
with only `mypy` skipped.

## Checklist

- [x] My code follows the project's style guidelines
- [x] I have performed a self-review of my code
- [x] I have made corresponding changes to the documentation
- [x] I have added tests that prove the feature works

feat: add differential network capture harness (#761)
## Summary
- add a containerized differential network capture harness for Claude
Code direct vs Claude Code routed through Headroom
- capture both Headroom client-side traffic and Headroom upstream
traffic with sanitized mitmproxy JSONL output
- add `headroom capture network-diff` to compare captures and produce
Markdown/JSON reports, including Anthropic tool-count/tool-byte deltas
for deferred-tool investigations
- add an on-demand GitHub Actions workflow for the harness; it only runs
via `workflow_dispatch`, with live Claude Code/Anthropic capture gated
on `ANTHROPIC_API_KEY`
- document the workflow and ignore generated capture artifacts

## Validation
- `C:\git\headroom\.venv\Scripts\python.exe -m pytest
tests/test_network_diff_capture.py`
- `ruff check headroom/capture headroom/cli/capture.py
tests/test_network_diff_capture.py`
- `ruff format --check headroom/capture headroom/cli/capture.py
tests/test_network_diff_capture.py`
- `C:\git\headroom\.venv\Scripts\python.exe -m mypy
headroom/capture/network_diff.py headroom/cli/capture.py`
- `docker compose -f
docker/differential-network-capture/docker-compose.yml --profile run
config`
- `docker compose -f
docker/differential-network-capture/docker-compose.yml --profile run
build claude-direct`
- `docker run --rm -e CLAUDE_COMMAND="claude --version"
headroom-network-diff-claude-direct:latest`
- parsed `.github/workflows/network-diff-capture.yml` with PyYAML and
confirmed manual-only trigger

Live Claude API capture was not run locally because `ANTHROPIC_API_KEY`
is not set in this environment. The workflow can run it manually in
GitHub Actions when that secret is present; otherwise it emits a visible
skip warning and uploads a skipped artifact.

## Notes
- Full pre-commit mypy still fails on unrelated Windows `fcntl`
attributes in `headroom/subscription/tracker.py`; the feature commit
skipped only that hook after narrow mypy passed for the new modules.
- `tests/test_release_workflows.py` has two Windows-local failures
because it shells out to a missing Unix/Rust command; unrelated workflow
checks in that file passed before those failures.
- Motivated by
https://github.com/chopratejas/headroom/issues/746#issuecomment-4651276818
/ Issue #746.

fix(copilot): restore generic endpoint for non-subscription OAuth (#610) (#612)
* fix(copilot): restore generic endpoint for non-subscription OAuth (#610)

0.23.0 re-pointed the shared Copilot OAuth branch from the generic
api.githubcopilot.com host to the account-specific endpoints.api host
returned by /copilot_internal/user, and made resolve_copilot_api_url
ignore the GITHUB_COPILOT_API_URL override whenever a token resolved.

That change was meant to add --subscription, but it also altered the
pre-existing non-subscription OAuth flow that worked on 0.22.4. The
account host does not serve newer models (e.g. gpt-5.4) on the responses
API, so wrapped requests began failing with unsupported-model errors
while plain Copilot and 0.22.4 kept working.

Restore 0.22.4 routing for non-subscription OAuth (generic host, still
overridable) and keep account resolution only for --subscription.
resolve_copilot_api_url now honors GITHUB_COPILOT_API_URL first, so the
override escape hatch works for every path. BYOK is unaffected.

Add a regression suite that mocks a successful user-info response, the
real-world path the prior test never exercised (it relied on the network
call failing in CI and falling back to the generic host).

* fix(copilot): route subscription + OAuth through the generic host (#610)

The 0.23.0 endpoint resolution derived the Copilot API host from
/copilot_internal/user (endpoints.api), which returns a segmented host
(e.g. api.individual.githubcopilot.com) that does not serve newer models
on the responses API and is not the host the official Copilot client
routes with (that comes from the token-exchange endpoint). --subscription
used the identical resolution, so it carried the same latent regression
as the non-subscription OAuth path.

Make Copilot host resolution override -> generic for BOTH --subscription
and the implicit OAuth path, and stop using user-info to route. Accounts
that require a dedicated host (enterprise / data residency) pin it via
GITHUB_COPILOT_API_URL. resolve_copilot_api_url no longer makes a network
call; _fetch_copilot_user_info is retained for token validation.

Update the subscription smoke tests that encoded the old account-host
assumption, and add wrap-level + unit coverage that --subscription routes
to the generic host even when user-info advertises an account host, and
that the GITHUB_COPILOT_API_URL override flows through both paths.

* docs(copilot): document generic-host routing + enterprise override (#610)

Spell out the routing contract introduced by the #610 fix so enterprise
users have a supported path. Headroom routes wrapped Copilot hosted
traffic (--subscription and OAuth) to the generic api.githubcopilot.com,
and accounts on a dedicated host (Enterprise Cloud data residency, egress
proxy) pin it via GITHUB_COPILOT_API_URL.

- copilot --help: note the generic host + GITHUB_COPILOT_API_URL override.
- TESTING-copilot-subscription.md: add "API host & Enterprise / data
  residency" section; correct the stale api.*.githubcopilot.com claim; and
  invite enterprise tenants who want token-exchange-based auto-detection to
  open an issue.
- integration-guide.md: short hosted-host + override note in the Copilot
  section.

265554d4ad fix(cli): proxy/perf/wrap UX cleanup + perf --hours correctness
Address user-reported UX gaps across the CLI surface:

- code-aware: add --code-aware/--no-code-aware (+ HEADROOM_CODE_AWARE_ENABLED env)
  to the Click CLI. PR #411 had added these only to the orphaned argparse main;
  the user-facing CLI couldn't reach the flag. Banner status text "remove
  --no-code-aware to enable" referenced a flag that didn't exist — fix to point
  at the actual flag/env. Surface code-aware in the click banner and add
  print_banner=False plumbing to run_server so the click path doesn't print
  two banners back-to-back.

- --mode: hide alias clutter via metavar=[token|cache] and rewrite help to
  lead with the two real modes. Legacy aliases (token_mode/token_savings/...)
  still validate.

- perf --hours: was documented but ignored. Records are now actually filtered,
  the report shows the actual time-range covered, and the count of records
  filtered out (so users can tell when raising --hours helps).

- perf TOIN: replace the hash-keyed pattern dump with a strategy-distribution
  view + recommendation-eligibility from the live store — actionable signal
  rather than opaque rows.

- code-graph: clarify in --help that it indexes cwd / project root.

- wrap: spell out supported tools, wrap-vs-proxy distinction, and that
  `headroom wrap opencode` isn't a thing (use `proxy` directly for opencode;
  openclaw is not opencode).

- mcp: note that mcp__headroom__headroom_retrieve is correct MCP namespacing,
  not a doubled-prefix bug. Renaming would break the proxy's tool injection.

- LLMLingua cleanup: remove [llmlingua] extra from pyproject (no live code
  uses it). Delete wiki/llmlingua.md and clean retired flag/class references
  in 6 other wiki pages. Point at [ml] (Kompress) where ML compression is
  documented.

- init -g openclaw: strip mcpServers from existing plugin entries before
  re-writing — newer openclaw schemas reject it, leaving stale entries from
  older installs unhealable. Pinned with regression test.

Tests: mock_run_server signatures in two existing tests accept **kwargs
(needed for the new print_banner plumbing). New test for the openclaw
mcpServers strip. Full suite: 4847 passed, 262 skipped, 0 failed.

feat(proxy): track Codex WS sessions and cancel relay tasks deterministically
Unit 3 of the Codex proxy resilience plan. Eliminates the "aged process
has leaked relay tasks" hypothesis by making every WS session explicitly
tracked and both relay tasks deterministically cancelled when either
exits.

- New headroom/proxy/ws_session_registry.py: dict-backed
  WebSocketSessionRegistry + WSSessionHandle with register /
  deregister / attach_tasks / snapshot. Deregister is idempotent and
  clears relay-task references so coroutine frames are not retained
  past session end.
- HeadroomProxy exposes proxy.ws_sessions so /debug/ws-sessions
  (Unit 5) can read the live snapshot.
- handle_openai_responses_ws now registers on websocket.accept()
  success and deregisters in the outermost finally so no leak can
  survive handshake-phase, mid-stream, or upstream-error paths. The
  session_id / termination_cause is threaded through both relay
  halves and both sides raise asyncio.CancelledError cleanly.
- Replaced asyncio.gather(_client_to_upstream(), _upstream_to_client(),
  return_exceptions=True) with explicit asyncio.create_task(...)
  (named codex-ws-c2u-<sid> / codex-ws-u2c-<sid>) +
  asyncio.wait(FIRST_COMPLETED) + cancel-and-await on the survivor.
  Termination cause is classified as client_disconnect /
  client_error / upstream_disconnect / upstream_error /
  response_completed from which task completed first plus inline
  error captures from the halves.
- Prometheus metrics: new active_ws_sessions and active_relay_tasks
  gauges plus ws_session_duration_ms_{sum,count,max} histogram
  bucketed by termination cause. Mirrors the Unit 2 stage_timing_*
  shape.

Preserved: upstream WS retry loop, WS→HTTP fallback, memory-context
timeout, compression pipeline, Unit 2 stage timings. Memory-tool
execution inside _upstream_to_client still runs when the client task
exits first; however, if the client disconnects *before* the upstream
emits response.completed, pending memory writes in `pending_fcs` are
dropped (unchanged from prior behavior — a crashing upstream has the
same effect). Note: handle_openai_responses (HTTP, line ~800) is a
single-shot HTTP request; lifecycle tracking isn't added there
(scope boundary).

Tests:
- tests/test_ws_session_registry.py: 8 registry unit tests
  (register/deregister idempotency, snapshot shape, attach merging,
  reference release).
- tests/test_openai_codex_ws_lifecycle.py: 6 integration tests
  using real relay tasks (only upstream WS endpoint mocked):
  happy-path, failing-test-first "client disconnect cancels upstream
  relay within 100 ms", upstream-closes-first, upstream-error mid-
  stream, handshake-failure deregister, 50 concurrent sessions.
- Regression: test_openai_codex_ws_timings, test_openai_codex_routing,
  test_proxy_codex_route_aliases, test_ws_memory_relay all pass.
- Tests pass under python -W error::RuntimeWarning (no "coroutine
  was never awaited").

bde7aa9c30 fix: align docker image versions with releases
Derive the exact Docker image version from the release tag or manual
workflow input, sync versioned files in the build workspace before the
image build, and publish an explicit matching image tag.
